Frequently Asked Questions

How do I know which cylinder fits my Case dozer?

Fitment depends on your model, serial number, and blade configuration, since cylinders changed across dozer generations. Match your existing cylinder dimensions and part number to what we list, or confirm with our parts team at (800) 909-7060.

Do you sell seal kits separately from the cylinders?

Yes. We carry seal and rebuild kits on their own for rebuilding worn cylinders, as well as complete cylinder assemblies when a rebuild is not practical.

What causes a Case dozer blade to drift down?

Blade drift is usually caused by worn cylinder seals allowing internal bypass. Replacing the seal kit or the full cylinder restores holding pressure. We carry both options for these dozers.

Should I rebuild or replace a leaking hydraulic cylinder?

If the cylinder bore and rod are in good shape, a seal kit is the more economical fix. If the rod is scored or the barrel is pitted, a replacement cylinder is the better choice. We offer both for Case dozers.
